To my horror today, I discovered that StackMobile was happily serving up content from the newest Stack Exchange site. (StackMobile has a cron job that runs daily, updating the list of sites using the API.)

So, to the point of my request - can we please add a flag to the /sites route that signals content that might be inappropriate for some users (since Stack Exchange reaches a broad range of users)?

Edit: after further thought, I remembered that this domain will also show up in /users/{ids}/associated. I'm not sure how that one can be resolved. Perhaps an app-specific flag can be set indicating whether such content should be exposed to the app.
